Car overheating

[GulfCoastGTS]

Just after my clutch/flywheel install, overheated. The radiator is full, no leaks, fans come on. Dunno. Anyone have any idea? We think its the thermostat, as one radiator hose is very hot and the other is cool. But why would this not be working all of the sudden, at 25k miles. We checked all the thermostat connections (its the thing beside the battery, right?) and they were good. Tell me what you think it is please. Thanks.

Could be that you have some air bubbles somewhere, may just need to bleed it out thoroughly with the front of the car elevated. Or somethign stupid like someone stuffind a shop rag ina radiator hose and forgetting it there.

They didnt even touch the radiator. but the day before I was being stupid and the radiator drained about 1/2 gallon. I refilled, could this have caused air bubbles? How do I bleed it? The mechanic said something about that. Thanks Griffin.

Yeah - that definitely could/would have caused some bubbles to enter the system. Take the radiator cap off, jack the front of the car up, and run it till it gets good and hot. rev the engine a little bit now and again (not much). If you jack the front up enough the bubbles will work their way out. As this happens the coolant level drops. whenever it drops add some coolant. After a while all the bubbles will have worked their way out and the level will no longer drop. Once done close the cap top off teh resivoir and let the car cool overnight. In the morning go check the level again, if it is below where it needs to be add coolant as necessary.

and are ya sure they didn't take the radiator or any of its hoses loose? They may very well hace done so for easier access to the shift linkage or some such.

Thanks griffin. I did this, drove it a little and it jumped one notch above normal temp and then back down. I checked it again and there needs to be some coolant added, so Im waiting for it to cool so i can add it. Thanks for the help. Oh yeah and there is a procedure under the hood how to do this, instead of jacking it up, it says unbolt the coolant reservoir and pull it up and set it on the hood latch. Same thing as your idea pretty much I guess. Thanks for the help.

Yup - the idea is to make it the highest point on the engine. I usually don't tell epople to do it that way because I don't want them to kink the hoses or pour 200 degree coolant on themselves.
